“…In contrast, Walter found diseconomies in German transportation systems, concluding that there should be competition rather than consolidation of services [16]. Di Giacomo and Ottoz and Ottoz and Di Giacomo analyzed the urban and intercity bus systems, concluding that cost savings are sensitive to model specification [17,18].…”

This paper analyzes the joint cost structure of electricity and natural gas distribution investments. Assessing the joint costs is critical for urban development and public policy regarding competition at the local level. The paper accounts for the urban and geographic factors at the local level, while the previous literature primarily used company-level data with a few or no site-specific variables in joint cost analyses. An empirical analysis of the multi-utility capital costs suggests that the local urban and geographic conditions affect such costs, with economies of scope present in electricity and natural gas both in terms of total costs and underground investment costs. Hence, the joint service provision makes economic and environmental sense for urban policy makers.

The main purpose of this study is to investigate how governance factors affect technical inefficiency in public utility firms. Inefficiency analysis in public utilities so far has focused mainly on industry-level treatments such as competition policy and regulations. However, since these industry-level treatments incur significant government costs and are difficult to monitor closely, management-level corporate governance, which has been widely discussed in private firms, has been attracting increased attention in recent years. In our analysis, we examine the effects of various shareholders as governance actors on technical inefficiency in public utilities. By using a panel data of 369 Japanese firms in seven public utilities from 1989 to 2015, we estimate the stochastic frontier production function. The main findings are as follows: (1) some governance factors clearly reduce inefficiency; as ownership by domestic companies and individual shareholders increases, the technical inefficiency of a public utility firm decreases. (2) However, we cannot determine the effects of foreign shareholders and financial institutions. These actors can have different effects depending on the situation. (3) Industry-level factors such as regulation and competition are shown to increase inefficiency. This indicates that conventional industry-level involvement is no longer effective in public utilities and & Fumitoshi Mizutani that in the efficiency analysis more attention must be paid to the managerial improvement of public utilities.
